Abstract

An extrudate in the form of a film of a copolymer of ethylene and <alpha>-olefin of 3 to 10 carbon atoms, which displays a specific density of 0.910 to 0.94 g/cm<3> and Mz/Mw of 4 to 10; in which the film displays a throw impact resistance DDI of 50-800 (when measured with ASTM D-1709), a turbidity larger than 15 (when measured with ASTM D-1003) and a gloss [ASTM D-2457] lower than 50.
